Spectrum-efficient correlation pattern for quality evaluation of Scutellariae Radix / 中草药

ABSTRACT

Objective: To establish a new mode for quality evaluation of Scutellariae Radix objectively and effectively. Methods: To collect Scutellariae Radix extensively, prepare test liquid of every sample, examine its HPLC fingerprints and pesticide effectiveness, and then correlate the HPLC fingerprints with the inhibitory rates by mathematics. Results: The other 20 batches of Scutellariae Radix were examined. The bias proportions of the inhibitory rates between the ones calculated by the established mathematical model and the ones from experimental measurement were less than 10% in all, there were 15 samples whose bias proportions are less than 5%. Conclusion: The mathematic model can basically be used to evaluate the efficacy of Scutellariae Radix by HPLC fingerprints.
